This application is a continuation of U.S. patent application Ser. No.13/444,714, entitled “AUTOMATIC SENSOR CONTROL PANEL,” filed on Apr. 11,2012, which claims the benefit under 35 U.S.C. §119(e) to U.S.Provisional Patent Application No. 61/609,152, entitled “AUTOMATICSENSOR CONTROL PANEL,” filed on Mar. 9, 2012, the disclosures of whichare expressly incorporated herein by reference in their entireties.

BACKGROUND OF THE DISCLOSURE

1. Field of Disclosure

This disclosure relates to an infra-red touch free sensor and controlpanel, and more specifically, to an infra-red touch free sensor andcontrol panel for faucets or other plumbing fixtures.

2. Background

The use of automatic faucets and showers, also known as hands-freesystems, have increased in popularity in recent years. These hands-freesystems use infra-red touch free sensors to operate the water flow. Theappeal and recent popularity of these systems may be attributed to thelack of knobs or levers needed to operate the faucet. Traditionalfaucets need a certain amount of force exerted on the knobs or leversfor water to start flowing. But in the case of sensor operated faucets,no force is needed because the water flow begins in response to a user'shand entering a field of detection of the faucet's infra-red sensor.

Additionally, the physical manipulation of the knobs or levers mayfacilitate cross contamination of germs and bacteria. The germs andbacteria may be harmful to humans and dangerous in sterile environmentssuch as a hospital.

Furthermore, over time, knobs and levers may become loose and worn out.Accordingly, a typical water dispenser system may not accurately deliverhot water or cold water when the knobs or levers wear out.

Thus, it is desired to provide a hands free system that accuratelydelivers water. However, traditional hands free systems only include awater on and water off function. Moreover, these traditional hands freesystems do not provide a function for adjusting the water temperature.Therefore, it is desired to provide a hands free solution that offers asolution to adjust the water temperature and another solution to adjustthe water flow.

DETAILED DESCRIPTION OF THE ASPECTS

The detailed description set forth below in connection with the appendeddrawings is intended as a description of various configurations and isnot intended to represent the only configurations in which the conceptsdescribed herein may be practiced. The detailed description includesspecific details for the purpose of providing a thorough understandingof various concepts. However, it will be apparent to those skilled inthe art that these concepts may be practiced without these specificdetails. In some instances, well known structures and components areshown in block diagram form in order to avoid obscuring such concepts.The infra-red touch free control panel allows the user to acquire theirdesired water settings in one single step or in incremental steps usinginfra-red touch free sensors.

Several aspects of a hands-free system will now be presented withreference to various apparatus and methods. These apparatus and methodswill be described in the following detailed description and illustratedin the accompanying drawings by various blocks, modules, components,circuits, steps, processes, algorithms, etc. (collectively referred toas “elements”). These elements may be implemented using electronichardware, computer software, or any combination thereof. Whether suchelements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

According to one solution, the hands-free system may include a controlpanel installed in proximity to or on a plumbing fixture, such as afaucet or shower head. The control panel may include a series ofinfra-red touch free sensors for controlling various water settings.

For example, the control panel may be installed on adjacent to theplumbing fixture, such as on the countertop of the kitchen sink or thedeck of a bathroom vanity. The control panel is connected to a controlbox consisting of a water mixing chamber. The water mixing chamber isdefined within the control box and is connected to the hot water supplyvalve and the cold water supply valve via a hose, such as a stainlesssteel water supply hose. The output from the water mixing chamber isconnected to the faucet. The control panel may be powered with an ACadapter or with batteries.

In one aspect of the present disclosure, the computer control moduleturns the water flow on or off when the user holds an input device, suchas the user's hand, over the face of the control panel. The infra-redtouch free sensors on the face of the control panel define a specificfunction when water is flowing and a different function when water isnot flowing.

The control panel includes infra-red touch free sensors, emittermodules, and receiver modules. The infra-red touch free sensors, emittermodules, and receiver modules are built into individual clustersassociated with a light emitting diode (LED). According to one aspect,various clusters on the control panel may be arranged in multipleformats, for example, the clusters may be arranged based on the desiredoperations and functions.

In one aspect, the user may hold their hand over a first specific side,such as a left side, of the control panel to activate a first functionwhen the water is off. In this example, the water may be output from thefaucet once the first function is activated. The user may then operatevarious sensors on the control panel to adjust the water settings, suchas the temperature or volume of water flow. The current water settingsfor the first function may be saved when the water is turned off. Itshould be noted that in this disclosure, turning the water off refers toa scenario when the water is not output from a water output unit,furthermore, turning the water on refers to a scenario when that wateris output from the water output unit.

According to present aspect, when the water is off, the user may holdtheir hand over a second specific side, such as a right side, of thecontrol panel to activate a second function. In this example, the wateris output from the facet when the second function is activated. The usermay then operate various sensors on the control panel to adjust thewater settings. The current water settings for the second function aresaved when the water is turned off. The first function and the secondfunction may be preset or set by a user.

The various sensors are connected to a computer control module.Specifically, a sensor control board relays a signal to the computercontrol module when the sensors are activated. The computer controlmodule transmits the received signal to the water control valve and thecorrect water mixture is dispensed from the faucet according to theuser's request.

The infra-red touch free sensors may simulate a full functiontraditional knob and lever faucet using a nonlinear digital method. Theinfra-red touch free sensors may also simulate a full functiontraditional knob and lever faucet using an incremental method.

As illustrated in FIG. 1, an aspect of this disclosure provides acontrol panel 100 in a housing. The housing may be waterproof and madeof plastic, brass, aluminum or other material that is sturdy andmoisture resistant. As illustrated in FIG. 1, the control panel 100 isinstalled adjacent to the faucet 200. Furthermore, an independentinfra-red touch free sensor 105 may be defined on the control panel 100

FIG. 2 illustrates various hardware elements of a hands-free system. Asillustrated in FIG. 2 the faucet 200 is connect to the control box 300via a water supply hose 174 connected to a water outlet 164.Furthermore, a hot water inlet 165 is connected to a hot water supplyvalve 155 via a hot water supply hose 175. Additionally, a cold waterinlet 166 is connected to a cold water supply valve 156 via a cold watersupply hose 176. Moreover, the control panel 100 is connected to thecontrol box 300 via a controller cable 101

Furthermore, as illustrated in FIG. 2, the control box 300 may bepowered via a low voltage AC adapter 109 that is connected to anelectrical outlet 110. Additionally, the control box 300 may be poweredvia a battery box 309 containing batteries, such as four AA alkalinebatteries or a lithium-ion battery.

FIG. 3 illustrates elements of a control panel according to an aspect ofthis disclosure. As illustrated in FIG. 3, infra-red touch free sensors111-119 may be defined on a sensor control board 102. The infra-redtouch free sensors 111-119 emit a light from an emitter module andreceive light at a receiving module. Specifically, the infra-red touchfree sensors 111-119 employ active infrared technology for sensing apresence of an object as opposed to a movement of an object. Theinfra-red touch free sensors 111-119 actively emit infrared light andactively wait for the light to return. In this disclosure the termsensor will refer to an infra-red touch free sensor.

In the present aspect, the emitter module may constantly emit infraredlight in a blinking method. Additionally, the receiving module mayalways be ready to receive the blinking light that is reflected from anobject, such as a hand. The sensor control board 102 may transmit afirst signal to the control box 300 via a controller cable 101 when thereceiving module receives the blinking light reflection and may transmita second signal when the receiving module no longer receives theblinking light reflection.

Accordingly, the sensors 111-119 relay commands to the sensor controlboard 102 in response to receiving an input from the user. Anindependent infra-red touch free sensor 105 may be defined on a side ofthe control panel 100. The independent infra-red touch free sensor 105is not defined on the sensor control board 102, however, the independentinfra-red touch free sensor 105 may be connected to the sensor controlboard 102 and may transmit signals similar to the sensors 111-119. LEDs141-149 associated with the sensor may omit light under control of thesensor control board 102. The sensors 111-119 and LEDs 141-149 areprotected by a surface 103 that may be scratch resistant, such as glassor acrylic.

It should be noted that in a typical infra-red touch free system, thesensors are not defined within close proximity. That is, sensors placedin close proximity may interfere with each other and cause inappropriatereadings due to the interference. The present disclosure provides asolution to mitigate the interference and thereby allow the sensors tobe placed in close proximity.

In the present disclosure, in order to avoid interference, the receiversfor each sensor are installed in a very specific and precise manner tomitigate the potential interference. Furthermore, the power for eachreceiver is reduced. The reduction in power may be achieved via the useof resistors and capacitors.

FIGS. 4A-4C illustrate various perspectives of the control panel 100.Furthermore, FIGS. 5A-5D illustrate different perspectives of thecontrol box according to an aspect of the disclosure. The control box300 may be a waterproof material such as plastic. The control box 300may house a water mixing control valve 301 (FIG. 7) and includes a hotwater inlet 165, cold water inlet 166, and water outlet 164.

FIGS. 6A-6B illustrate connections to the control box according to anaspect of the disclosure. As illustrated in FIGS. 6A-6B a water supplyhose 174 is connected to the water outlet 164. Furthermore, a hot waterinlet 165 is connected to a hot water supply hose 175. Additionally, acold water inlet 166 is connected to a cold water supply hose 176.Moreover, the control panel 100 is connected to the control box 300 viaa controller cable 101. Furthermore, the control box 300 may be poweredvia a low voltage AC adapter 109 that is connected to an electricaloutlet 110.

FIG. 7 illustrates internal parts for the control box according to anaspect of the disclosure. As illustrated in FIG. 7, the control box 300may house a water mixing control valve 301. The water mixing controlvalve 301 controls the hot water and cold water received from the mainwater supply and distributes the mixture to the faucet. The water mixingcontrol valve 301 includes a primary water mixture control cartridge 306and a secondary water mixture control cartridge 307. The primarycartridge 306 and secondary cartridge 307 are controlled with the use ofmicro gear motors 303 and 304. The micro gear motors 303 and 304 receivecommands from the computer control module 305. The water mixing controlvalve 301 also includes a thermocouple 308 to record the temperature ofthe water in water mixing control valve 301. The thermocouple 308 isalso attached to the computer control module, such that the watertemperature is monitored by the computer control module 305 and thewater's temperature is regulated to achieve the user's desired watertemperature setting. According to one aspect, the computer controlmodule may control the LEDs on the sensor control panel 102 to visuallyindicate the water temperature.

As illustrated in FIG. 7, the sensor control board 102 is connected tothe computer control module 305 in the control box 300 via thecontroller cable 101. The computer control module 305 in the control box300 receives and transmits signals from the sensor control board 102.Furthermore, the computer control module 305 may receive power from apower cord 107 connected to the AC adapter 109 and/or batter box 309.

According to an aspect of the disclosure, as illustrated in FIG. 8, anindependent infra-red touch free sensor 105 may be defined on a side ofthe control panel 100. The independent infra-red touch free sensor 105may activate or de-active the water flow from the faucet 200. Forexample, the faucet 200 may output water when the independent infra-redtouch free sensor 105 senses a presence of an object, such as a hand, inthe detection area 100 d. The faucet 200 will continue to output wateruntil the object is no longer sensed in the detection area 100 d. Theautomatic water output function may be deactivated via at least onesensor defined on the sensor control board 102. The sensors utilized todeactivate the automatic water output function may also reactivate theautomatic water output function.

According to one aspect, a specific LED on the control panel may lightup while the water is off and the automatic water flow sensor 105 isdisabled or re-enabled. For example, the specific LED 140 may be one ofa plurality of LEDs 140-152 (FIGS. 9A-9E). The specific LED may be litfor a specific time period or may be lit during the entire duration whenthe water is off.

As previously discussed, the automatic water output function may beactivated or deactivated via at least one sensor 111-119 defined on thesensor control board 102. As an example, to activate automatic wateroutput, the user may use their hand to cover the face of the controlpanel 100. Specifically, in this example, the automatic water output isactivated when the user activates all of the sensors 111-119 on thesensor control board 102 (FIG. 9A). Furthermore, in this example, thecontinuous water flow is deactivated when the user reactivates all ofthe sensors 111-119 on the sensor control board 102. While the water isturned on, the current state of water is displayed via at least one LEDdefined one the sensor control board 102.

According to another aspect of the present disclosure, a single sensoror a plurality of the sensors define a specific function when water isbeing output from the faucet and a different function when water is notoutput from the faucet. For example, activating a first sensor 118 (FIG.9A) while the water is not being output may activate or deactivate theautomatic water flow. Furthermore, in this example activating the firstsensor 118, while water is being output from the faucet, may activate apre-defined combination of water temperature and water flow.

According to another aspect of the present disclosure, a single sensoror a plurality of the sensors may be associated with specific waterfunctions. For example, when the water output is off, the user may holdtheir hand over a specific side, such as the left side, of the controlpanel to activate a first preset function. Once this function isactivated, the water may be output from the faucet. As an example, watermay be output when a plurality of sensors 112, 115, and 119 (FIG. 9A)are activated. Furthermore, in this example, the LEDs associated withthe current water temperature and water volume may be lit when the wateroutput is activated.

As yet another example, when the water output is off, the user may holdtheir hand over a specific side, such as the right side, of the controlpanel to activate a second preset function. Once this function isactivated, the water may be output from the faucet. For example, watermay be output when a plurality of sensors 111, 113, and 116 (FIG. 9A)are activated. the water starts flowing and specific LEDs may be lit.Furthermore, in this example, the LEDs associated with the current watertemperature and water volume may be lit when the water output isactivated.

According to the aspects discussed above, the control panel 100 maysimulate a traditional lever faucet using a nonlinear digital solution.Specifically, a single sensor or a plurality of the sensors definedwithin the control panel 100 may be associated with specific functionsto adjust at least water temperature, water flow, or a combinationthereof. The specific functions may be pre-defined at the time ofmanufacturing or set by the user. Moreover, the LEDs associated witheach sensor may be lit to represent different temperatures and waterflow levels.

Various examples of configurations for the sensors 111-119 and LEDs140-152 are illustrated in FIGS. 9A-9E. It should be noted that theexamples of FIGS. 9A-9E are examples of various configurations and thesensors and LEDs are not limited to the example configurationsillustrated in FIGS. 9A-9E.

As previously discussed, a single sensor or a plurality of the sensorsdefined within the control panel 100 may be associated with specificfunctions to adjust at least water temperature, water flow, or acombination thereof. For example, in one aspect, as illustrated in FIG.9A, a first sensor 111 and a first LED 141 may be associated with a coldwater temperature and low water flow, a second sensor 112 and a secondLED 142 may be associated with a hot water temperature and low waterflow, a third sensor 113 and a third LED 143 may be associated with acold water temperature and medium water flow, a fourth sensor 114 and afourth LED 144 may be associated with a water temperature (betweenmid-hot and warm) and medium water flow, a fifth sensor 115 and a fifthLED 145 may be associated with a hot water temperature and medium waterflow, a sixth sensor 116 and a sixth LED 146 may be associated with acold water temperature and high water flow, a seventh sensor 117 and aseventh LED 147 may be associated with a warm water temperature and highwater flow, an eighth sensor 118 and an eighth LED 148 may be associatedwith a mid-hot water temperature and high water flow, and a ninth sensor119 and a ninth LED 149 may be associated with a hot water temperatureand high water flow.

In another example, with regard to FIG. 9B, a first sensor 111 and afirst LED 141 may be associated with a cold water temperature, a secondsensor 112 and a second LED 142 may be associated with a warm watertemperature, a third sensor 113 and a third LED 143 may be associatedwith a mid-hot water temperature, a fourth sensor 114 and a fourth LED144 may be associated with a hot water temperature, a fifth sensor 115and a fifth LED 145 may be associated with a low water flow, a sixthsensor 116 and a sixth LED 146 may be associated with a small waterflow, a seventh sensor 117 and a seventh LED 147 may be associated witha medium water flow, and an eighth sensor 118 and an eighth LED 148 maybe associated with a high water flow.

In yet another example, with regard to FIG. 9C, a first sensor 111 and afirst LED 141 may be associated with a no hot water flow, a secondsensor 112 and a second LED 142 may be associated with a low hot waterflow, a third sensor 113 and a third LED 143 may be associated with asmall hot water flow, a fourth sensor 114 and a fourth LED 144 may beassociated with a medium hot water flow, a fifth sensor 115 and a fifthLED 145 may be associated with a high hot water flow, a sixth sensor 116and a sixth LED 146 may be associated with a no cold water flow, aseventh sensor 117 and a seventh LED 147 may be associated with a lowcold water flow, an eighth sensor 118 and an eighth LED 148 may beassociated with a small cold water flow, a ninth sensor 119 and a ninthLED 149 may be associated with a medium cold water flow, and a tenthsensor 120 and a tenth LED 150 may be associated with a high cold waterflow.

In another aspect, a plurality of sensors may increase or decrease atleast a water temperature, water flow, or a combination thereof. Forexample, with regard to FIG. 9D, while water is being output from thefaucet, the user may simultaneously activate a first plurality ofsensors 111 and 113 to increase the water temperature, alternatively,the user may decrease the water temperature by simultaneously activatinga second plurality sensors 112 and 114. In another example,simultaneously activating a first plurality of sensors 111 and 112 mayincrease the water flow and simultaneously activating a second pluralityof sensors 113 and 114 may decrease the water flow.

According to another aspect, a plurality of LEDs on the control panelmay indicate the current state of a water temperature or water flow. Forexample, as illustrated in FIG. 9D, a first set of LEDs 141-146 indicatethe water temperature and may illuminate from one direction to anotherdirection to indicate the current state of water temperature. Forexample, the right-most LED 141 may be associated with the lowest watertemperature and the left-most LED 146 may be associated with the highestwater temperature. Furthermore, a second set of LED's 147-152 may beassociated with the water flow. Thus, in this example, the water flowLEDs 147-152 may illuminate from one direction to another direction toindicate the current state of water flow. Specifically, the right-mostLED 147 may be associated with the lowest water flow and the left-mostLED 152 may be associated with the highest water flow.

As yet another example, with regard to FIG. 9E, while water is flowingfrom the faucet, the user may simultaneously activate a first pluralityof sensors 111 and 113 to increase the hot water volume, furthermore,the user may decrease the hot water volume by simultaneously activatinga second plurality sensors 112 and 114. Additionally, the user maysimultaneously activate a third plurality of sensors 111 and 112 toincrease the cold water volume and simultaneously activate a fourthplurality of sensors 113 and 114 to decrease the cold water volume.

According to another aspect, a plurality of LEDs on the control panelmay indicate the amount of hot water or cold water that is currentlyflowing from the faucet. For example, with regard to FIG. 9E, a firstset of LEDs 141-146 on the control panel may indicate the hot watervolume. Specifically, a first LED 141 on the bottom may be associatedwith a hot water volume of zero (e.g., no hot water is being output)while a second LED 146 on the top represents the highest hot watervolume. The hot water volume LED's illuminate from the bottom to the topto indicate the current state of hot water volume. Additionally, the asecond set LED's 147-152 on the control panel may indicate the coldwater volume. For example, a third LED 147 on the bottom may beassociated with a cold water volume of zero (e.g., no cold water isbeing output) while a fourth LED 152 on the top may be associated withthe highest cold water volume. The cold water volume LED's illuminatefrom the bottom to the top to indicate the current state of watervolume.

It is noted that the sensor and LED configuration are not limited to theconfigurations disclosed above and may be any configuration for settingor adjusting water flow and temperature.

As another example, while the water is being output, the user mayactivate the ninth sensor 119 (FIG. 9A) to set the temperature to a hottemperature and the water flow to a high water flow. Moreover, inresponse to activating the ninth sensor 119, the ninth LED 149associated with the ninth sensor 119 will illuminate in red and theother LEDs may be dimmed. Alternatively, if the user selects the thirdsensor 113 to acquire cold water with a medium flow, the third LED 143associated with the third sensor 113 may illuminate in blue and theother LEDs may be dimmed.

According to one aspect, when a water setting is activated, the LEDsassociated with all of the settings from the current setting to thelowest setting will be activated. For example, with regard to FIG. 9B,the faucet may output medium hot water when the user activates the thirdsensor 113. Furthermore, the third LED 143 associated with the activatedthe third sensor 113 will be activated, furthermore, the LEDs associatedwith lower settings may be activated. In other words, LEDs associatedwith water temperatures that are less than the medium hot watertemperature selected by the user will be activated. Moreover, as anexample, if the user selects the fifth sensor 115 to achieve a low waterflow, only the fifth LED 145 will illuminate because the low water flowmay be the lowest setting available.

According to another aspect, with regard to FIG. 9B, the user may adjustthe water temperature or the water flow in a single nonlinear step. Forexample, if the current water flow is set to a low water volume, theuser may activate the eighth sensor 118 to request a high water flow. Inthis example, the user is not required to activate the sixth sensor 116or the seventh sensor 117. Rather, the user may directly adjust the flowfrom low to high and bypass intermediary settings.

According to another aspect, as illustrated in FIG. 10, an existingfaucet 1000 may be adapted with the control panel 100 and control box300 in order to utilize the hands-free system. Specifically, asillustrated in FIG. 10, the hot water inlet 165 is connected to the hotwater supply valve 155 and the cold water inlet 166 is connected to thecold water supply valve 156. The water outlet 164 is connected to afirst inlet pipe 1004 of the existing faucet 1000 and a second inletpipe 1002 is blocked via a shut off valve 201.

FIG. 11 illustrates a block diagram of a hand-free system according toan aspect of the disclosure. As illustrated in FIG. 11, the hand-freesystem may include LEDs 1101, infra-red touch free sensors 1102, asensor control board 1103, a computer control module 1104, athermocouple 1105, a primary micro-gear motor 1106 associated with acartridge 1107, and a secondary micro-gear motor 1108 associated with acartridge 1109. As discussed with other aspects of the disclosure, theinfra-red touch free sensors 1102 may detect an object to receive aninput and signals may be transmitted to the sensor control board 1103.The sensor control board 1103 may relay the signal to the computercontrol module 1104. The computer control module may then adjust thewater settings using a primary micro-gear motor 1106 associated with acartridge 1107 and/or a secondary micro-gear motor 1108 associated witha cartridge 1109. A thermocouple 1105 may monitor the water temperatureand relay the temperature to the computer control module. Additionally,the computer control module may transmit the water temperature and thewater flow to the sensor control board 1103 so that the sensor controlboard 1103 may control the LEDs 1101 to indicate at least the currenttemperature or water flow.
